Accounting Standards Board (ASB) of ICAI has provided Format of Financial Statements for NPOs in absence of standard template for financial statements specially for society and trusts. The format is best practice and should be followed by NPOs specially society and trust as standard templates. You may consider introducing these from FY 2024-25 since audit process must be on.

Yes, you are correct, to be treated as presentation and rreporting best practise as I mentioned. Someday they will become mandatory. Better to adopt from this or if already drawn from next year. Since it is coming from ASB, ICAI, many auditors are asking their NGO clients to draw in these formats.
